Prerequisites

The following are required to run queue source connector:

• kubemq cluster
• kubemq-targets deployment

Configuration

Queue source connector configuration properties:

Properties Key	Required	Description	Example
address	yes	kubemq server address (gRPC interface)	kubemq-cluster:50000
client_id	no	set client id	"client_id"
auth_token	no	set authentication token	jwt token
channel	yes	set channel to subscribe
sources	no	set how many concurrent sources to subscribe	1
response_channel	no	set send target response to channel	"response.channel"
batch_size	no	set how many messages to pull from queue	"1"
wait_timeout	no	set how long to wait for messages to arrive in seconds	"5"

Example:

bindings:
  - name: kubemq-queue-elastic-search
    source:
      kind: kubemq.queue-stream
      name: kubemq-queue
      properties:
        address: "kubemq-cluster:50000"
        client_id: "kubemq-queue-elastic-search-connector"
        auth_token: ""
        channel: "queue.elastic-search"
        sources: "1"
        response_channel: "queue.response.elastic"
        batch_size: "1"
        wait_timeout: "5"
    target:
      kind: stores.elastic-search
      name: target-elastic-search
      properties:
        urls: "http://localhost:9200"
        username: "admin"
        password: "password"
        sniff: "false"
